Does fitness attenuate the relationship between changes in sitting time and health-related quality of life over time in community-dwelling older adults? Evidence from the EXERNET multicenter longitudinal study 2019 Objective: To assess the relationship between fitness levels and components, sitting time and health-related quality of life (HRQoL), over time among community-dwelling older adults. Methods: Three different sitting trajectories were calculated: (i) no change; (ii) decrease; and (iii) increase in ST, between baseline and follow-up. Fitness was assessed using the aerobic capacity, upper and lower limb strength, and total fitness. Participants were classified into higher (75th percentile or above) or lower (below 75th percentile) fitness levels, using the fitness tests. HRQoL scores at follow-up were compared to the three different sitting time trajectories within and across both the higher and the lower fitness groups for each of the three fitness indexes. Results: Greater HRQoL scores were observed in those participants that decreased their ST as compared with those increasing their sitting time over time for participants classified in the lower end of their aerobic capacity or total fitness index. No differences were detected in HRQoL scores in people classified in the higher fitness level group for any of the fitness indexes. Participants that increased or did not change their sitting time and who were classified in the higher fitness end of aerobic capacity and total fitness index self-reported higher HRQoL scores when compared with those in the lower fitness end. Conclusion: Increased sitting time over time is associated with poorer HRQoL in older adults. Higher fitness levels could help attenuate the negative impact of sitting over time. info:eu-repo/grantAgreement/ES/MECD/EXERNET-DEP2005-00046 info:eu-repo/grantAgreement/ES/MINECO/DEP2016-78309-R info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.773 2019 HEALTH POLICY & SERVICES 16 / 87 = 0.184 2019 Q1 T1 PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH 34 / 169 = 0.201 2019 Q1 T1 HEALTH CARE SCIENCES & SERVICES 31 / 102 = 0.304 2019 Q2 T1 PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH 59 / 193 = 0.306 2019 Q2 T1 1.116 2019 Public Health, Environmental and Occupational Health 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion del Pozo-Cruz, B.
